Thank you Frank for your quick reply. You are right. I was expecting dbus to modify the config file and bring up the export which was wrong assumptions from my end. When I added an EXPORT block in export.conf and used the dbus-send command later, I could add the export without any issue. [root@localhost ~]# cat /etc/ganesha/export.conf ## Configure an export for some file tree ... EXPORT { ## Export Id (mandatory, each EXPORT must have a unique Export_Id) Export_Id = 3; ## Exported path (mandatory) Path = /home/ganesha_1/; ## Pseudo Path (required for NFSv4 or if mount_path_pseudo = true) Pseudo = /home/ganesha_1/; Transports = "TCP"; ## Exporting FSAL FSAL { Name = VFS; } } [root@localhost ~]# sudo dbus-send --print-reply --system --dest=org.ganesha.nfsd /org/ganesha/nfsd/ExportMgr org.ganesha.nfsd.exportmgr.AddExport string:/etc/ganesha/export.conf 'string:EXPORT(Export_Id=3)' method return time=1591935638.984428 sender=:1.175 -> destination=:1.208 serial=36413 reply_serial=2 string "1 exports added" [root@localhost ~]# showmount -e Export list for localhost.localdomain: /home/ganesha_nfs_v3 (everyone) /home/ganesha_nfs_v4 (everyone) /home/ganesha_1 (everyone) [root@localhost ~]# As you have suggested, I have tried SIGHUP as well and it is also working fine for me.
